Replace the restrictive AFM with a much larger mass air sensor. Much less complicated than Megasquirt and makes nearly as much power. Included:
1. Arc2 conversion box with independent offset, linearity, gain, and response adjustments
2. MAF installed in the lid of a M20B25 airbox (includes a 3.0” to 2.5” reducer/coupler)
3. Misc wiring
4. Installation instructions
I tried to leave as much wiring as I could, but you may need to extend it depending on where you want to place the Arc2a. I mounted it below the ABS ECU (bracket included), but others have positioned it in the center console opening or in the glove box. The later two installs use less wiring, so you might be OK there. Note that this kit does not include an air/fuel ratio monitor. There are many inexpensive gauges available for this, I would *highly* recommend one be installed along with the MAF conversion. New this kit retails $733 ($832-$99 for the monitor originally included). I’m selling everything shown for $175.
